Now I’ve only had Fleck softener in operation for a couple of months. But so far it has been working perfectly. I did have to call the seller during installation with a question about water being retained in the salt tank (my previous softener was a Sears and it never had standing water in the salt tank like this one does. The person I talked to was extremely helpful as well as pleasant to talk to. He also walked me through the program cycles (his help was actually more helpful than the YouTube video I watched). Our water is moderately hard. This softener might have been a little overkill, but I prefer that to struggling with equipment that can hardly keep up.
